Escalier Hélicoïdal Industriel

What Escalier Hélicoïdal Industriel does

Escalier Hélicoïdal Industriel is a French custom metalwork fabricator founded in 1979 and headquartered in Villevaudé, near Paris, operating as part of the FHMETAL-GROUP industrial platform. The firm designs, manufactures, and installs bespoke metal staircases in helicoidal (spiral), straight, and balanced configurations, complemented by railings, guardrails, and ancillary metal structures such as bridges and catwalks. Since inception it has delivered over 12,000 staircases, reflecting a long-standing craft specialization in curved handrail fabrication and complex geometry that few generalist metalworkers replicate.

The business operates a project-based, quote-driven model: each engagement is initiated via a sales-led consultation, scoped against technical and aesthetic requirements, priced on a custom basis, and executed with a stated lead time of 4-6 weeks after deposit. Installation is performed by in-house crews within an approximate 200km radius of Paris, while the broader commercial footprint extends to Belgium, Luxembourg, Switzerland, and Africa. The customer base spans private homeowners (the primary segment), industrial and ERP facilities, architects specifying projects, and cultural or commercial venues such as opera houses and bakeries.

The firm sustains a digital presence through a website, blog, and social media channels to support lead generation, and has formalized data-processing compliance via a CNIL declaration. It does not disclose revenue, headcount within the 11-50 employee band, or external funding, and operates as a privately-held specialty manufacturer rather than a venture-backed or platform business.

Core offering

Escalier Hélicoïdal Industriel (EHI) designs, fabricates, and installs custom-made metal staircases — helical, straight, and balanced — together with custom guardrails, handrails, and bridges/catwalks. Every project is bespoke, manufactured in steel with optional wood, glass, or PMMA components and finishes such as raw, galvanized, lacquered, or powder-coated. The company serves private homeowners, architects, industrial, and commercial clients across France and selected export markets, with installation services in northern France.

Product overview

EHI (Escalier Hélicoïdal Industriel) is a manufacturer of custom metal staircases and guardrails founded in 1979, operating as part of FHMETAL-GROUP. The company offers three core staircase product lines: (1) escaliers hélicoïdaux — their flagship helical/spiral staircases with a central shaft (fût central) or without, in various diameters and configurations including multi-level stacked flights; (2) escaliers droits — custom straight staircases typically with flat or square-tube stringers; and (3) escaliers balancés — balanced staircases with debillarded curved stringers. Complementing the staircases, EHI fabricates custom guardrails (garde-corps) and handrails (rampes) in multiple styles (bar vertical, horizontal lath, debillarded), as well as bridges and catwalks (passerelles). All products are custom-made to order, manufactured at their workshop in Villevaudé (near Paris) and installed either by their own teams (northern France) or delivered nationwide via specialized carriers. The company follows a four-step customization process: Forms (shapes), Steps (marches), Railings (rampes), and Finishes (finitions).
